CAR STOP.

Application filedv September T o aZZ whom, it may concern:

Be it known that I, PAUL KALISCH, a citi- Zen of Germany, residing at Antigo, in the county of Langlade and State of Wisconsin,

I have invented certain new and useful Improvements in Car Stops, of which the following is a specification.

This invention -relates to a novel and improved carstop to be used on railroads to stop cars at a certain predetermined point, especially during the car switching operations, and it is the principal object of the invention to provide a can-stop which 1s readily manipulated and of a simple and inexpensive construction, yet durable and eiiicient.

' Another object of the invention is to provide a car-stop of this character which has an exchangeable wedge-shaped tongue adapted to make the stop a gradual one.

A further object of the lnvention is the provision of a car stop, the body of which is suitably grooved on its lower face to provide lateral depending flanges adapted to engage over the'rail head and allowing the attachment of the wedge-shaped tongue.

lt is also one of the objects of the invention to provide the carstop with a handle allowing a convenientoperation of the stop. It will be clear that any number of these stops may be used in the daily operation and switching of cars, particularly freight cars which must be stopped at certain predetermined spots, for instance, in front of the platforms'of ware-houses, switches, etc.

These and other objects of the invention and advantages thereof will become more fully known as the description thereof proceeds, and will then be specifically pointed out in the claim.

In the accompanying drawing, foi ming a material part of this disclosure Figure 1 is a side elevation of a freight car with va stop constructed accordin to the 45 invention in place on one of the lai s.

Figure 2 is a side view on an enlarged scale illustrating part of the car wheel with -a stop constructed in accordance .with the present invention in operative position.

The wheels 10 of a freight or other rail- 25, 1924. Serial No. 739,756.

road car 11 of any customary construction and type run on rails 12 and adapted to engagethe wedge-shaped tongue 13 of thecarstop gradually increasing in thickness towards its rear end.

The body 14 of the car-stop has its lower face grooved as indicated at 15 for the reception of the thicker end of the tongue 13' attached to the bottom of the groove by means of a "plurality of fastening devices, for instance as shown, by threaded bolts 16 having heads in form of nuts 17 at their lower ends which are adapted to be embedded in a central longitudinal groove 18 provided in the lower face of the tongue 13. The side walls of the roove 15 in the body of the stop are shape to form depending lateral ianges 19 and 2O engaging over the' head 21 of a rail 12.

At its rear upper end the'body 14 is equipped with a convenient and suitable handle 22 to allow a ready operation and handling of the stop while a stop shoe or tongue 23 is secured with its lower end in the stop bod, 14, while its upper end is shaped to fol ow the contour` of a railroad car wheel as indicated at 24.

The operation o1" the device will be quite evident from the above description, the stop is placed on the Tail at the place where a car pushed oli by a switching engine, etc., is to stop, and it will be clear that the engagement between the car Wheel and the gradually increasing wedge-shaped tongue will tend to slow down the movement of the car which will then be finally stopped by the engagement of its wheel iange with the projecting stop shoe 23.

Changes, such as fall within thev scope of the appended claim, can be made in the general arrangement and in the construction of the minor details of the device without departure from the spirit-of the invention.

Having thus described my invention, what I claim as new and. desire to secure by Letters Patent, is

Car stop comprising a substantially plane- .shaped body having a lower groove extending longitudinally, anges formed by the groove to laterally' engage the rail head, a wedge-shaped tongue in said groove gradually increasing in thickness towards the rear and extending for a Considerable distance beyond the front end of said body, said tongue having a groove in its lower rear face, a plurality ofvscreW-bolts securing said tongue to said body, and nuts in the groove of said tongue on said bolts, a handle on the upper rear face of said body, and a curved stop at the upper front end of saidl body having an upper end curved to conform to 1U the curvature of a car Wheel.

In Witness whereof I have affixed my signature.

PAUL KALISCH.
